operation.

A further object of the present invention is l the provision; of awindow lock, which, in"

addition to the facility of limiting movement of the upper andlowersashes, mayat the same time serve as anan'ti-rattling device.

and Others that willappear "as the n'ature'of the invent-ion is betterunderstood the same consists in the novel construction, combination andarrangement of parts hereinafter more fully described, illustrated inthe accompanying drawing and pointed out in the appended claims. p Inthe-drawing forming a partof this zip 'plication and in which likedesignating char- -acters=refer to corresponding parts throughout theseveral views, a 7 "Figure l is an elevational view of two window sasheswith the lock shownin an operative position; a v V Figure 2'is across-sectional view on line 2-2 of'Figureli Figure 3 isacross-sectional view on line 3-3 of Figure 1; I

Figure 4 is an elevational perspective view of the window look while thesame remains in'anopen inoperative position; and Figure 5 is across-sectional view through the window lock on line'5 5 ofFigure 3.

Referring in detail to the present drawing there is 'shown therein theusual window frame with the upper and 'lower sashes therewithin forupright sliding movement. The lower sash includes the usual horizontalbar 11 and oneof the upright bars 12. The upper sash includes the lowerhoriz'ontalsash bar13 and one of the upright bars 14. The two vsashesare [spaced on horizontal plane with spacing strip 15, projecting fromthe window frame 10, interposed 'therebetween.

With the above general object-s in view a hinge: connection} with plate19: p i

dicated by 16, and a window'pane' in the up a per sashisindicated by 17.Adapted' for mounting by screws 18, "passing through suitable apertures,is asuhstantially rec'tan gular plate .19. Formed at. the horizontal 55,

edges thereof are outwardly extending flanges 20, forthe purposehereinafter de- 7 scribed' Near its'one'vertioal edge and sub- Istantially at the central portion thereof said plate '19 is providedwith 1 a substantially to square opening 21,:whioh at one of its :sidesis defined by anoutwardly projecting strip 22, for the purpose whichwill be later appar cut. it i The window lock" proper cooperatinglwithplate 19 is also formed out ofra single metal sheet suitably formedtoinclude acentral'loop or ridge 2.3 horizontally disposed while thewindow lock remains 'inl'an operative posi tion ina'window, saidridge23'forming-astop 7 0" for the upright relative sliding' movementrofthe two sashes.- Extending from said'ridge -23"on' both sides is a pairof tapered plates 24, each ofwhioh'at one of its cornershaving lugs25formed thereinffor insertion within a corresponding aperture formed atoneend ofeach flange 20 forjthepurpose of-*forming For the purpose of;interlocking "the two hingedly connected portionsof the lock, or inother words,to bring about the operative or inoperative position ofthelock, a suitable latching device is provided between said two 7portions. 7 Said latching device includes-84 substantiallyrectangularbodygportion 26 in-' serta ble within the outer free ends of the i saidwalls of ridge 23. Said rectangular porv tion of the latching device isprovided with lateral depressions 27.; Theside walls of said ridge 23are clinched with theresultant inner bulges28 on the inner faces ofsidesof ridge 2.3,- which aresadapted toenter -depressions 27, by means. ofwhichl said body portion'26 remains in pivotal arrangement .1 withinsaid ridge 23. i a i i Said body portion 26 is provided with mg 29 whichis co-extensive with ridge 23. Interposed ibetween sa idlug 29 and apexof a ridge 23 is acoil spring 30 for normallyurging said lug away'fromsaid ridge 23. One

of the ends of said coil spring .30 is in rigid engagement with lag 29for the purpose of preventing displacement of said COll spring.

' Rigidly formed with said body portion 26,

and extending from one end of said body portion 26, and in an angularportion with re- 'spect to said lug 29 is hook 31 which remains in atransverse relation with ridge 23, which r the latchingidevice so thatby manual angular shifting of knob 32 away. from the adja-- centiend ofridge 23, and its side walls hook 31 may beidisengaged from bulgingstrip 22 .1111 fthefp'late 19,.whereby the two. hingedlyEconnectedportions of the lock-may be shifted to an inoperative positionshown on Figure 4, When said two cooperating parts of the lockringdevice are closed, hook 31 will enter opening :21 and will automaticallyspring into 7 an-engaging position with 'strip 22 by virtue ofthe'pres'snre anda-ctionof spring 30 at lock .29; WVhen in an .operativeposition shown onFig's. 1, 2 and 3, ridge 23. and its sidewalls willform a stop for the horizontal upper sash bar of the lower window sashpreventing the relative upright shifting movement-0f the upper and lowersashes, as seen-on Fig. 2. .When thetwo hingedly connected portions ofthe lock aredisen- 'gaged by a ngularly shifting knob 22'for disengaginghook 31 from strip 32, the mov-' "able part of the locking device may bebrought to the; position shown on Fig. 4, whereby the lock'will remainin an inoperative position and away from the path of movement of theupper horizontal bar of the 'lower'window sash, as indicated by dottedlines on Fig. 3. f In that latter position ridge 23 will face thewindowpane 17 of the upper window'sash, as shown by dotted lines on Tofacilitate manual withdrawal of the outer shifting movement of lock onwithdrawal of hook 31from engagement there- -of with strip 22 onmanually angular-1y shifting of knob 32,.inwar dly disposed bulges 33are provided at substantiallycentral portions of side walls of ridge 23,whichbulges faciliftate the manual grasp of the ridge forthe purposeofmanual withdrawal of the hinged movable part of the lock from plate19.

The objectof making plates 24 tapered or of the body portion 26 ofthetionally engage the adjacent face of the tapered plate 23, as seen onFigure2, in consequence whereof the two sashes-W111 be caused to remaininrigid relative adj ustment,

Thus, the relative movement and consequent rattling will be prevented. I

Flanges 20 prevent any displacement of theshiftable portion of the lockin relation with plate 19. Any attempt of breaking the-lock V byforcibleshifting ofa window sash against r a lock will be preventeddueto the factthat flanges 20 preventlrelative displacement of theshiftable portion'of the lock relative to its position with plate 19, asis apparent from Figure2. i f While there is described herein apreferred embodiment of the present invention,,it-.is nevertheless to beunderstood vthat'minor changes, may be made therein, without departingfrom the spirit andscope of the in vention as claimed. l I
